应用软件技术提高彩电FBT测试台抗干扰性能

对于工业实时控制和测试系统,噪声干扰是最令人困扰的问题之一,常常需要从各个方面采取措施,提高系统的抗干扰性能。软件抗干扰不改变硬件环境,不需要对干扰噪声进行精确的定位、定量分析,实现灵活方便,对消除干扰引起的一些暂态性故障有明显的效果,是计算机自动测控系统的主要特点和优势之一。本文介绍了FBT测试台中存在的和可能存在的一些功能性故障,论述了处理这些故障的各种软件方法。这些方法可以推广到其他一些计算机自动测控系统。

Application of Software Techniques to Improving Anti-disturbance Performance of the Colour TV FBT Testing Station

For industrial time controlling and testing systems, noise disturbance is one of the most perplexed problems. Therefore, steps must be taken in all aspects before the improve- ment of the anti-disturbance performance. No ambient hardware can be varied by software anti-disturbance conducted. One of the thief characteristics and superiosities of the computer-controlled testing systems without accurate location of the noise disturbance and quantitative analysis so as to realize the flexibility has an apparent effect on the temperery ac- cidents caused by elimilating disturbance. Here in this article, some functional barriers ex- isting in FBT testing station will be described, as well as a variety of software methods to deal with the problems, The methods will be extended to the computer automatically controlled testing systems.
